Part Number: ISOW7841
My customer is adopting ISOW7841F. Schematic is as below. ADUM5401 is pin compatible with ISOW7841F. Input is 3.3V. When test VISO between PIN16/15, the voltage is not stable as below. But when change to ADUM5401 solution, the VISO output is good. Please help comment the reason. Thanks a lot!
In reply to Abhi Aarey:
Thanks for quick response!
In fact, it should be not ripple in VISO output. It is not regular as ripple. Also the PK to PK value is about 300mV. It is not acceptable by customer.
